Remember parkour? Remember ghost riding the whip? Behold: both at once.
This video shows that when three guys are in a car with no driver, the obvious thing is to do crazy stunts on and around the car. It was made by Sunstance Over Style, which is a Los Angeles-based group of skaters, martial artists, parkour guys, and all-around awesome dudes you should never trust with your car.
